Question

what is Debereiner's law of traids? explain with the help of one example of a Debereiner's triade​

Answer 1

Explanation:

Debereiner's law of traids state that the atomic mass of the middle element of a traid is the arithmetic mean of the atomic masses of the other two elements . For example - In the traid of lithium , sodium and potassium . The atomic mass of lithium is 7 and the atomic mass of potassium is 39 .

Answer 2

Explanation:

The atomic mass of the middle elements of the traid being equal to the arithmetic mean of the atomic masses of the other two elements.

For example: Alkali metal group (Dobereiners triad ):

Lithium is the 1 st element , sodium is the middle element whereas pottasium is 3rd element of the traids.
